SPLICE BAR Application filed September 22,1931. Serial No. 564,387.

This invention relates to railway rails and joints, and more particularly to the splice bars used in splicing the ends of rail sections.

The primary object of the invention is to provide a splice bar which willbe exceptionally strong and durable, and one which will compensate for the movement between rail sections due to expansion and contraction, thereby eliminating any possibility of the splice bars buckling. V

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the l and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departlng from the spirit of the invention.

Referring to the drawings:

Figure 1 is a side elevational view illustrating splice bars constructed in accordance with the invention, a portion of one of the splice bars being broken away. V

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Referring to the drawings in detail, the reference character 5 designates the adjacent ends of rail sections which have been brought together in the construction of a track. 1

Since the splice bars forming the subject matter of this invention, are identical on both sides of the rail, the splice bar at one side of the rail will be described in detail.

The splice bar comprises sections 6 and 7 respectively, the sections being formed with bases 8 to accommodate the bases of the rail sections used in connection therewith.

As clearly. shown by the drawings, the sec tion 7 is formed with an extension 9 -substan tially square in cross section, the extension being fitted in a bore or opening formed longitudinally of the section 6, the bore or open-. ing conforming in shape to the shape of the extension 9, so that a close fit between the ex 7 tension 9, and opening or bore, will be insured at all times.

details of construction hereinafter described The splice bar sections areof'widths to fit snugly'between' the base of the; rail sections, and under surfaces of the ball or tread ofthe'rail sect ions. I f

Elongated openingsare formed inthe'iex 5'5 tension 9, which elongated'openings register with openings formed in the cooperating splice bar section and web ofthe rail with whicht-he splice bar is used. I

' Thus it will be seen that due to thisconstr'uction, movement ofyonej section of th' splice bar with resp'ect'to the other section will be permittedi'whe'n the'rail sections 61x pand or'contract under heat andcold;

As shown by'the' drawings, the extension 9 :of onesplicebarat' oneside'of the rail, isexe tended in one direction, whilefche extensionf9 of the splice bar or section at the opposite side of the rail is extended in the opposite direction, thereby provid nga splice bar ment of the rail sect ions,la utone which will be exceptionally strong and durable." a -Ifdesired,-the sp licebars-m'ay be arranged 5 so--t-hat the"extensions"9""extend in the same direction, without departing from the spirit of the invention.

Thebolts which are indicated by the reference character 10 are of the usual and well known construction, and are provided with nuts 11 for tightening the bolts in position.

Cut out portions 12 are provided in the sections of the splice bar, for the reception of the usual spikes employed in securing the 35 rails to the ties of the track.

The cut out portion in the section 6 of the splice bar is elongated to permit of movement of the splice bar sections upon expansion or contraction of the rail sections. 0

Having thus described the invention what is claimed is:

1. A splice bar comprising a pair of cooperating sections arranged end to end, a bar extending from one of the sections and extending into one end of the adjacent section, and bolts extending through the sections and rails with which the splice bar is used.

2. A splice bar. comprising a pair of sections, one of said sections having a longitudi-' 0 nal bore, a connecting bar extending from the adjacent section and fitted in the bore to slidably connect the sections, bolts extending through the bar and said connecting bar having elongated openings to receive the bolts.

3. A splice bar comprising a pair of sections arranged end to end, one of the sections having a bore extending longitudinally there of from one end of the section, a connecting bar carried by the adjacent section and fitted in the bore to slidably connect the sections, and bolts for connecting the splice bar to th adjacent ends or" the railway rails.

4. A splice bar comprising a pair of cooperating sections to be fitted over the sides of railway rails, one of said sections having a longitudinal bore square in cross section, an extension extending from the adjacent splice bar section, said extension being square in cross section, to fit snugly within the bore, said extension having elongated openings, the adjacent section of the splice bar having openings aligning with elongated openings to receive bolts, and said bolts extending through openings in railway rail sections.

5. A splice bar comprising a pair of sections arranged end to end, one of the sections having a bore extending longitudinally through the center thereof, an extension ex-' tending from one end of the adjacent section, and disposed within the bore, bolts extending through the extension and adjacent section to secure the sections of the splice bar together, and said extension having elongated openings to receive the bolts and allow movement of one section with respect to the other section.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
